2003 Yukon Denali Navigation Radio

So after buying my 2003 Denali I found that GM is offering an integrated Navigation radio for the Denali's , Escalades, and I think Hummers. I don't like the idea of an aftemarket nav unit because of the high cost and non factory look. So I contacted my dealer and several others for prices on the factory installed integrated Navation radio that would work with my onstar and XM Radio. Every dealer told me that they could NOT order that radio and that it would not be compatible with my vehicle. I said BS and contacted both GM tech engineers and Delphi Inc (who make the radio). They could not provide me with an answer and advised me to trade my truck in for another 2003 or 2004 that has the Nav radio installed from the factory. So I did my own research on the my trucks wiring and found no difference between my truck and others with the factory navigation unit. So I found a Navigation unit on E-Bay for 1300.00 and ordered it. It had previously been inside an Escalade so I did not know if it would work. I received the unit and it plugged in and powered up with no problems other than the theft protection engaged. I installed the supplied GPS antenna that mounts inside the dash and off to the dealer I went. The dealer reset the radio with the Tech 2 scanner/reader for one hour labor cost ( B.S ) and it works perfectly with my XM and Onstar. In addition it is under warranty from GM and looks factory installed. I thought this would be interesting info for other Yukon Denali owners. I do not know if this unit would work in a standard Tahoe or Yukon but I would bet it would as long as the truck is 2003 or newer. The electronics in the pre 2003 trucks is totally different and this radio will not work. Below is a pic of the radio I took out and a pic of the new Navigation radio I installed.

That's like what I did. Except I have a 2002 Pontiac Grand am GT1. The unit works, but for some odd reason, it stays in night mode all the time when the car is on. I got mine from a guy who visits the another forum I frequent. He got it from a wrecked '04 Buick Rendezvous. I paid $500 for it. I couldn't pass this great deal up. :)

Anyway, what it doesn't have is the right gps antenna. I am trying to find out what the part # is for the correct gps antenna that hooks into this unit. I saw your unit on ebay and sent the seller an email asking what the part # was and he did not respond. So if you help me out here, do you know what the part # is? I am having a difficult time finding it. It's very frustrating. :(

Here are pics of the unit:

Had the dealer program the unit for my car. So it's unlocked. :)

I can not tell you anything about the GPS antenna. The dealers I contacted about this radio could not give me any info at all. I will call my buddy at a GMC dealer who may be able to find it but that is unlikely because he could not even get me an owners manual for it. I would try calling Cadillac dealers about the antenna, they seem to know more about this unit because it is being used in alot of their products. There has to be a way to find one !!!

That is sweet...I assume your steering wheel controls still work? I have a 2003 Tahoe Z71- might have to look into this

But you said you "installed the supplied GPS antenna that mounts inside the dash." The gps antenna I have has the part # on it. Was there a part # on yours? Also, was the wire and the gps antenna 1 piece or 2 pieces? The antenna I have needs a cable to attach to it and I don't think that is right.

Yes, the antenna mounts inside the dash above the radio and is connected to the radio with an attached wire and plug. The GPS antenna in actually mounted to a small metal piece that has a hole in it for securing it. I attached a picture of the antenna below. I would have to pull my radio to see if there is a part number on it but I don't think there is any numbers on it from what I remember. Hope this helps !! :smokin:

Yes, steering wheel controls still work fine along with Onstar and XM Radio if equipped. I will be listing one of these Nav radios on E-Bay next week with a buy it now of $1300.00 if interested. It includes a manual and Nav Map disc ver 1.0 but no GPS antenna. It came out of a totalled 03 Escalade last week and will have to be reset after being installed. :smile:

http://home.comcast.net/~krydz/Nav_Antenna.jpg

Yep, that's what I saw on ebay. It looks like there is a number printed on a label attached to the metal piece from what I can see. I see numbers, but can barely read it. :(

And that's not the part I have. I knew I had the wrong part. I have contacted dealerships and they either don't know, or give me the wrong part that they thing is right. I spent $60.00 on a cable that I thought attaches to the gps antenna I have. When it came in and I opened the box, I discoved that it is a cable assembly that hooks up various components including onstar. So I have searched and I come up with nothing.

It you can find a GPS antenna that has the same plug it should work. They are all designed the same from what I have been told. Have you contacted GMPARTSDIRECT.COM? They are really good at getting hard to find parts. http://www.gmpartsdirect.com

By the way, I can give you the link to the online manual for this unit. It's on my home computer though and i'm at work. I'll post it later.

No, I have not contacted gmpartsdirect about this. I did ask them to add a part # that I got from the dealership to their site. Which is the part that turned out to be wrong. I'll have to contact them about finding the gps antenna part. I doubt they will be able to find it. Why is GM so difficult with their electronic parts? It's terrible.

It is so difficult because the radio is produced by Delphi as part of a contract with GM and Delphi will not answer any questions regarding this unit or the parts related to it. GM is useless because they just plug the thing in and hope it works at the factory. No one could help me at all with this radio. I am just glad it worked when I installed it, now I have two of them !! Go Figure !!

Yeah, i've sent Delphi an email about the part # and they never returned an email.

I just bought an '03 Denali with the stock navigation unit... Do any of you guys know if the radio has a video input on the back of it? I want to add a back-up camera and integrate it into the stock screen. The install shop I went to said they weren't sure if there was a video input on the back pf the unit and if there wasn't they would have to send the unit out (for about 2 weeks) to intergrate the back-up camera to it. I would rather not do this since it will probably void the warranty. Thanks...

The radio does NOT have an aux video input on it. You can have it done here >>http://www.avelectronic.com/products.htm OR http://www.nav-tv.com/ . You have to send them your radio and they open it up and install the video in. At this point your warranty is GONE on the Navigation radio and you have to buy their video processing unit. Their unit takes the input from your DVD player, rear camera, TV tuner, etc and displays it on the screen of the navigation unit. It is very very trick but also very expensive. You will end up spending over $1000.00 for everything you need with labor but I hear the picture looks great. Also, this mod WILL void the warranty on the nav radio and remember GM is getting almost three grand for the stupid unit.

Ok guys, contacted gmpartsdirect about the part # for the GPS antenna and after several illustrations they sent me, the final one was the right one and I sent an email back to them indicating which part on the diagram was what I need. They sent me the part # and I verified it with a dealership. It is the part that I need.

The part # is: 15207447

How much $$ do they want for it ??

$45.25. GM list price is $90.50. That's how much you would pay at the dealer. I've ordered the part. Total price is $54.30 (due to shipping). Not bad.

By the way, the seller on ebay who sold the Navigation unit to copout221 finally sent back an email. In my email, I asked him what the part # was and he replied that he has the GPS antenna and would sell it for $150. I sent an email back to him saying that's an outrageous price. I also said that's rediculous and a ripoff. Have not received a response.

Yea, he was a bit strange. It was weird that he had over six of these radios for sale. I wonder where he got them ?? They are not that easy to come across !!! $150.00 for the antenna is a rip especially if you can get one from GM for $90.00.

How does the Navigation work in your vehicle? Does it operate like it should? Tracks as you drive and gives accurate results?

I like it but it has it's limitations on maps and the updated DVD map discs are way way overpriced IMO. Otherwise, I like the unit better than the last Lexus system I used in my GS400. The one I installed has been working great. I did have one incident after filling up with gas last week that the entire radio turned off while driving and reset itself for some unknown reason. Freeekn dealer could not provide me with an answer and said to bring the truck in if it did it again. It has been working fine since that day. I also noticed that there is weird background noise when the nav voice comes on or the onstar is activated. Sounds like engine noise !!!

I noticed that there is background noise when the second the screen comes on. If I turn the screen off (feature in the config), then the noise goes away. Also, the screen is acting funny. The color is now somewhat gold. Look at one of my pics and compare it to the others, that is the problem I am having. Sometimes, it is normal. Others, it just changes suddenly to a slight gold. I wasn't expecting this from such a nice unit. :(

I do wish it had the volume bar like my old head unit had.

Also, mine is practacally new. The Rendevous it came out of only had about 4000 miles. More or less. And it was an '04. So I have the latest DVD.

Hmmm, that is strange. I have not had any issues with the color of the screen but I can tell you that there are ton of bugs and issues with these radios from what I was told by a local A C Delco distributor that fixes all the radios in GM vehicles for my dealership. They are not yet authorized to touch these Nav radios because of how new they are and have been told they are "Full of Bugs." They told me that the radios are basically put together in pieces that just get replaced when they go bad.

Yeah, it was working fine for alittle over a month and then problems started to occur. One problem I forgot to mention is that all buttons except for the config button lock up sometimes. Meaning, they don't function when I hit them. I have to hit config. Then all the buttons start to function again. Very weird. I'm going to have to send the unit in. Which is unfortunate. I figured it had bugs. My step mom's '03 Navigator with CD based Navigation system has some bugs too. The screen would distort several seconds after power on and then go blank. This occurs once in a while. The screen resets with the start up screen showing up.

copout221-
Thanks for the info and the links... The systems in the links look great, but after reading the newer posts about how the unit functions, I definatly don't think I want to void my warranty! Unfortunatly, I havn't used the navigation yet because the dealer didn't have the cd when I picked up the truck. Said they had to order it and would have it by the time my plates came in. Thanks again...

It's here at last!!! :) It came in yesterday and I plugged it in and was quite disappointed when I saw it wasn't tracking my car real time. It would refresh every 1 min or so. I put in a destination and it still would refresh every one minute, more or less. Until I got onto the highway. When I looked down at the unit, it was tracking my car like it should. Then I heard the bell notification then the woman's voice said to get off at exit 22. And then it guided me to my destination. It works!!! :)
A nice feature is it shows you what street you are on, what building you are passing, what exit is coming up next if your on the highway, etc. I was in a local college area and it showed on the display that the building I was next to was the Main Administration Building. Pretty cool. :D

Hey, I read your post and was most excited to hear that! Could you let me know where you purchased that from or if you know of anywhere I may purchase the navigation unit - factory of course, thanks!

Here is one on ebay now with no bids yet >> Click Here for Nav radio auction (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&category=38653&item=2451797056) . If you can get this unit for under $1700.00 it is a good buy since it includes the antenna and DVD map disc. You would just need an owners manual. If I didn't already have one I would buy this unit in a heartbeat!! :bigthumb:

Also, you can order one brand new from Mike in parts at Cadillac of Menlo Park in California (650) 688-1543. He will sell you one for $1730.00 plus s/h BUT that does not include GPS antenna and DVD map disc. He only has a few left in stock.

I purchased the unit from a member of another forum. Got it for a great deal, $500. :)

There is a site that you can use to find just about any part from another vehicle. www.car-part.com (http://www.car-part.com)

There are several Navigations units that I found. The Nav that I have is found in '03 GMC Yukon, Cadillac Escalade, '04 Envoy, Trailblazer, Bravada, Rendezvous, Rainer, and several others. So those are the vehicles to search under.

Just a few quick questions for the experts in this thread:

1) I have an 03 Tahoe w/ XM radio and the bose speaker package. Is there an XM module I remove from my current radio and put it in the new radio? Or do I call XM and give them my new radio ID #?

2a) Where does the navigation DVD go? In the same slot that the audio CD's go? If so, it must then be imposible to listen to CD's and use the navigation at the same time.

2b) Can you listen to the radio/CD/XM etc while using navigation? Is there also voice guidance? Does it dim the music so you can understand the voice better?

3) How do you input destinations? Is there a remote or is it touchscreen?

Thanks all...

1. The XM module in tucked away in your dash and is specific to your Tahoe. It cannot be removed and used in any other GM vehicle. When you install a new radio the unit just has to be compatible with XM and will work fine with your existing module you currently have. The new radio (2003 and up) will have to be reset by a GM dealer at a small labor cost.

2a.The Navigation CD has to be in the radio for the Nav fuction to operate. My denali has an in dash 6 disc cd changer that works with the Nav fuction. I never remove the Nav disc but in your case I think you would have a problem unless you can install the six disc changer which I think is a difficult task.

2b. Yes you can listen to the changer, am/fm radio, XM, and onstar with the navigation fuction set for a destination. It has voice guidance that mutes the stereo so you can hear the directions. In addition, the nav screen shows you exactly where you need to go. Also, the steering wheel controls are still operational with this unit.

3. To input destinations, addresses, points of interests, telephone numbers, etc you simply use the small joystick on the face of the radio to select what you want and it calculates the route based on your preferences and your off. My last vehicle had the touch screen option and I hated it because the screen gets full of fingerprints and smudges that eventually damage the screen.

Also, this radio will work fine if you have a rear seat entertainment system installed, including DVD.

copout221: Thanks for your help.

I realized I forgot to indicate that I also have an in-dash 6 disc cd changer, but I assume that was all part of the factory radio (mine in the 2-din factory unit) - meaning when i remove the factory radio to install the nav, i assumed the changer would go with it. Is this not true? Are they separate units somehow? Or on your model is the cd changer separate from the 2-din (i.e. beneath the climate controls?). Thanks for your help!

Yes, your radio looks like this and you will lose the changer option if you replace it with the nav unit.

http://home.comcast.net/~copout221/6disc_radio.jpg


My in dash changer looks like this and is a seperate unit installed in a half din opening in the lower part of the center counsel. I don't believe you can install this unit in a Tahoe without doing some serious modifications to your wiring harnesses but I could be wrong.

Does anyone know if there is a way to unlock the DVD player in the Nav Radio to play other than map DVD's? BMW and others are able to do this although they don't "officially." I would like any info on this. I have an 04 Denali with the Nav radio and want to give it a try.

Yes it can be used to play DVD movies and display an image with an optional camera for the rear. The nav unit has to be removed and shipped to one of the places listed below. They open up the radio and modifiy it so it can accept video inputs. The entire setup will cost you over $1000.00. If you decide to do it post a reply about it so we know how it works.

Something to think about, for those of you who are putting the GM nav unit in a vehicle that originally didn't come with one factory-installed--IIRC the vehicles with the factory-installed nav units also have wheel sensors to aid in plotting vehicle location on the nav screen during those instances when the nav is not receiving a (or receiving a faint) GPS signal.

I don't mean to be a party-pooper but if you think about it, there will be times where your nav isn't gonna be fully functional--e.g., in a tunnel, dense forest, or downtown where there are lots of very tall buildings--and as such, won't be able to accurately plot your location on-screen. Other than that, it's still great that you guys can still get it to work at all. :iceslolan

I agree. My rule of thumb is if the XM radio stops working the Nav is probably not receiving a decent signal. Keep in mind this Nav unit searches for up to twelve GPS satellites at a time.

Our vehicles do have speed sensors. With the old radio factory radio and with the nav, there is a feature called speed compensated volume (SCV). That feature (which uses the speed sensors) monitors the speed of the vehicle and increases or decreases the volume according to the info it receives.

You will know when it is searching for a GPS signal because "GPS" shows up on the display. When it finds a signal, "GPS" is removed.

What I am getting at is that the Nav "CD" is actually a DVD. SO, if the Nav radio can read a DVD there may be an unlock code or something which can unlock the radio to play and display regular DVD movies/concerts, etc... I know people who have had the local BMW dealership enter in a code to unlock their DVD player in their Nav radio after buying a car. It is frowned upon, as it is illegal for a driver to be able to see a video while driving apparently. I know there must be some way to do this without sending the radio out, it is kind of like reprogramming it. My local dealer service advisor says that he is aware of such things, just not specifically with the GM Delphi unit yet as it is so new. Also, if they get a Nav radio with a glitch (which he says does happen), they pull it and replace it without even thinking twice about it.

No, I'm talking wheel sensors (or whatever it is that monitors wheel yaw, among other things), not necessarily speed sensors; the speed sensors you're referring to don't/won't (I could be wrong here) be able to tell the nav if the vehicle is turning, no? Unless your vehicle has these wheel sensors (or similar), I highly doubt that your nav will be able to continuously track your vehicle accurately if you lose GPS signal. :grinno:

True and I believe your right. I thought it had a built in gyro that does what you are describing but from my experience, that does not seem to be the case. Say I don't take a turn that the nav says to take. Well, it assumes i'm taking that route anyway and I watch the icon turn when i'm actually going straight. About 3-4 secs later, it corrects and goes back on track. So it isn't very accurate but it's still very usuable. My next will definately have Navigation that's for sure. I never get lost with this thing. :)

Hmmm, that is weird !! My nav unit does not do what you are describing. It tracks real time and if I dont't follow it's directions it continues to track my exact position while re-calculating a new route to get to my destination.

Is it possible to retrofit one of the newer XM capable and/or nav units into an 01 Denali? My cd changer looks just like the one copout posted above, and I don't think GM changed the dash layout on the newer Denalis did it? Thanks!

No, it cannot be done on any 2002 or older GM trucks because of the new serial bus communication standard that is now being used. Basically, the new radios have to read the vehicles vin # through the serial bus to operate. The radio locks in the vin number so the radio cannot be used in any other GM vehicle if stolen. Also, this new standard allows GM techs to program certain features of the radio and reset it through the OBD port with a scanner. Here is some more info on the new serial bus standard, it is a real pain in the A$$ !! Click on this link >> http://service.gm.com/gmtechlink/arcv_pdf/9_02_e.pdf and select "new radio requires reprogramming" . You need to have ADOBE to view it.

Thanks for the info. Guess I'll have to go with an add-on unit of some sort, or just wait until I trade her in for a new one. :(

Anyone know what the part number is for that navigation radio? I belive that its on a sticker on the back of the radio. The number for the cadilac is 15204334, but I am concerned that that one when started up will show the cadilac symbol. Also, I need the part number for the DVD as well.

I appreciate any help I can get.

Thanks,
Dave

It will not show the cadillac start-up screen. The one that I have was out of a buick and when I turn it on, it displays "PONTIAC." Appearantly, the unit reads a code that tells it what type of vehicle it's in and shows the correct brand start up screen.

The radio is the same for all the GM vehicles. If you install a cadillac nav radio into a GMC it will display GMC. It knows what type of vehicle it is in by the vin number. The radio does NOT come with the GPS antenna so you will need that to work also.

I'm looking for some info if any anyone can help that would be great. I have 2003 GMC Sierra CrewCab 2500HD. I bought the Nav radio, Nav disc, & Nav ant. I installed all of it and took it to the dealership to have them reprogram it with there Tech 2 device. After trying several times and calling GM tech support they concluded it couldn't be done. They said the problem was I had the wrong amp. GM tech support said that I needed an amplifier that comes out of a Denali or an Escalade. These amps have a class II data bus in them and my amp does not. The bad thing about that is that it cost $650.00 from the dealer and there is nothing saying it will work. Any input is welcomed.
Thanks

This is the first I have heard of the amp being different but it really does not surprise me. I would suggest finding the amp used and trying it. I am sure you could find it on e-bay or at http://www.car-part.com/ for a resonable price. If you don't have the bose system to start with you will NOT be able to get the nav radio to work even with a new amp. The entire structure of the Bose system is different.

I do have the bose system currently. I am searching for the part to try. Thanks for the link.

I do not have the bose amp. I have the monsoon amp and it works perfectly fine. I noticed a sound improvement over the old stock radio.

Question tfoster3. Does the radio turn on at all? If so, unplug the unit and let it sit for 1 min. Then plug it back in and turn the key to ACC. Do not turn it to ON. The unit should be fully functional in this mode. When you turn it to on, appearantly the BCM sends information to the radio at which point the radio locks out. At least that is what happened when my nav unit wasn't reprogrammed. Let me know what happens.

Question tfoster3. Does the radio turn on at all? If so, unplug the unit and let it sit for 1 min. Then plug it back in and turn the key to ACC. Do not turn it to ON. The unit should be fully functional in this mode. When you turn it to on, appearantly the BCM sends information to the radio at which point the radio locks out. At least that is what happened when my nav unit wasn't reprogrammed. Let me know what happens.


The radio turns on and off just fine. The problem I have is there is no sound from the tuner and no chimes. The tuner shows channel signal and also shows the text for the song and artist. The Nav portion works fine and there is audio with the Nav system. My vehicle didn't have OnStar or XM originally so maybe that has something to do with it.

The only thing I can think of is that the pins for the amp don't match up. Now i'm not sure if the nav unit requires an external amp but from my understanding, it does. But the oem external amps do not have the databus system. You just connect it and it works.

What I can't understand is why you need a bose amp. These new databus radios are suppose to detect what kind of amp is plugged in. When I disconnected my oem monsoon amp when I had the old stock radio in and I turned on the radio, I would see "BOSE" show up instead of "MONSOON."

I just purchased the 04 silverado SS ...equipped with the six disk indash xm bose system. First i must say for 42,000 one would think that this truck would be equipped with nav stock....but no. So now I am faced with the task it looks like u guys have been succesfull with.

ok the question is when u re3moved ur stock deck did the unit just plug and play with the existing harnress ....or did u have to cut and hardwire?

one more question is since mine is currently the six disk indash system and will be removed .....what changer can i hook up to this unit?

thanks for any help!!

If you use a factory replacement such as the Nav system it will be plug and play.
